1988 Ford 5.8L Calibration 8-64H-R00 VECI Label & Parts List (E8AE-9C485 AGA)

This document is a screenshot from motorcraftservice.com showing Ford calibration 8-64H-R00 for a 1988 model year light-duty truck with a 5.8L engine. The top portion reproduces the Vehicle Emission Control Information (VECI) label, which states the vehicle is equipped with EEC IV/EFI systems with non-adjustable idle speed/mixture, gives a five-step ignition timing procedure (disconnect SPOUT connector, set timing to 10° BTDC at normal operating temperature), lists spark plug ASF-32C gapped at .042-.046, catalyst equipment, calibration code E8AE-9C485 AGA, and emissions equipment code JFM5.8T5HZZ3 - AIP/EGR/EGS/TWC/FI. A vacuum routing schematic shows components including the FPR, EGR, throttle body, MAP sensor, carbon canister, air bypass valve, EVR, TAB/TAD solenoid valves, and vacuum reservoir. Below is a Calibration Parts List table giving name/description and Motorcraft service numbers for 23 emissions and engine-control parts, including thermactor valves and pump, EGR sensor and vacuum regulator, oxygen sensors (F-Series/U150 and Econoline), MAP sensor, fuel pressure regulators, throttle position sensor, distributor, coolant and air charge temperature sensors, and the EEC-IV processor (E8TZ 12A650-ANA). Useful for verifying correct emissions parts and timing specs for this 1988 5.8L calibration.
